Make sure the TH is level, then go to the right lower part of the screen. Touch the GPS, go to accelerometer , now calibrate. Do not touch anything till it is finished. It must be level. All should be well now.
Sounds like it might have dirt in the control. I think you found the problem in any case and I don't know of a good way to clean it. Probably best to call Yuneec and tell them what you have.
Not sure about the ST16, but it should be similar to doing the ST10/10+, see below! And good luck my friend! Sounds possible to fix!
Thanks, this looks like is a jammy stick on the ST16, the accelerometer calibration did not make any difference, I think something in the ST 16 is giving false inputs to the H.
I've just followed the video above; it worked almost fully; the menus are more or less the same on the ST16 compared to the one in the video.
I had to repeat the procedure a few times as either the camera or the rabbit slider ended up without their full range on the hardware monitor screen.
When starting, it seems that the camera slider needs to be up almost but not all the way up, and the rabbit slider to the bottom but not hard on the bottom. - In test, I ended up a few times with the camera on the H not tilting above 45 degrees or with the rabbit slider making continual bleeping noises, the same bleeping it makes when it's moved into and out of position, but the bleeping was on almost permeant - not pleasant.
Now I have finished the procedure with the camera starting on the H looking forward and it's slider almost to the top and this appears to give a good result.
The speed rabbit slider is now giving jerky increments to the top on the hardware monitor from where it is at it's new lowest position at about 20% from the bottom, hopefully this will not effect the flight characteristics of the H, but it's range seems almost as before.
I will give my dealer and or Yuneec a call tomorrow and see if there is a H specific written procedure or video, as it seems there are conditions specific to the H for the starting points of the sliders, other switches I started and finished in the off or how you would when taking off in angle mode.
After about the 5th re-calibration the fishy stick has settled down, so success there...
By the way, I noticed there are HDMI settings in this menu, maybe anyone who is having trouble with HDMI connections can find a fix here.
Thanks for all the help....
